My perspective on champion balancing

..... Why, why riot. I haven't been playing league for very long but have found some of your balance decisions very un-nerving. Fizz is still nearly unbeatable and has a button that nukes u, helps him escape, and makes him invincible. Tryndamere's kit is loaded with a crazy slow, heal, escape, free longer mobile zhonyas, and insane crit. yasuo can dash infinitely and 100-0 you with only a shiv. More than anything garen and mord are both bordering on immortal and deal crazy damage. One thing that really stuck out to me was the fact that in 5.17 you NERFED azir, and BUFFED fizz...... it disgusted me as a mid lane main. I cant play a nice game of my favorite champ (kennen) mid without dealing with a fizz that can jump on me and insta-nuke me with only q then e and there is almost NO way to defend myself because he can just run through my minions, become invulnerable and then get out nearly unscathed. I love this game to pieces and have spent a large margin of my free time playing it and would hate to see these overpowered champs get buffed as harder to play champs like azir are getting nerfed. (I also enjoy some azir from time to time, but once again fizz is there to rain on the parade by jumping over my ult, his 10 sec cooldown e is more powerful and can basically negate my 2 min ult.....) Anyway i hope you take my thoughts into account as you continue to champ champs and their kits and release new ones. (I first saw the "they're coming" icon today and have to say i am thoroughly elated for its release!) Sincerely, Cal
